如何通过使用数组和开关盒点击单个按钮来处理文本视图和图像，我需要Android中previos按钮的代码

极客！我是安卓系统的初学者。。。我正在我的应用程序中进行android的另一个活动，在这个活动中，我总共有10个视图(7个文本视图+2个图像按钮+1个图像视图(和两个图像按钮(即下一个和上一个(，我通过单击单个下一个按钮一次更改所有这10个视图，我使用了array和switch来更改文本值和图像。原因是所有的tex值彼此不同，但问题是我在它的UI.xml文件中使用了这些值中的第一个，而没有包含在array中，这就是为什么当我单击后退按钮时，它无法显示所有这些值的第一个值。其次，默认情况下，当用户第一次查看时，我还想看不见上一个按钮，当用户点击下一个按钮一次时，两个按钮都会显示出来，当用户第三次点击时，这两个按钮又会显示出来？我被困在这里，而且我不知道上一个按钮的正确代码(比如increment(，这就是为什么我没有在这里添加。若你们理解我想要做什么，那个么编辑我的代码或者发布具有相同功能的新代码。我们将感谢你的帮助。

  My Java Code:
  public class AlifPics extends Activity {
TextView text1;
TextView text2;
TextView text3;
TextView text4;

public void nextClick(View v) {
    try {
        switch (counter) {
        case 1: // first click
            text1.setText(textvalue1[0]);

            imgBut1.setImageResource(myImageButtonList1[1]);
            imgBut2.setImageResource(myImageButtonList2[1]);

        default:
            break;
        }
    } catch (Exception e) {
    }
    counter++;
}
// my previous ImageButton
public void previousClick() {
    try {
    } catch (Exception e) {
    }
}

}

根据您的代码，我的建议是：

定义您的计数器global和Static(在OnCreate之前(，使Value可靠
你可以将所有的文本保存到String.xml中，你的编码会更漂亮，你可以这样使用它们：

getResources((.getString(R.string.yourString(；
创建一个函数来处理create-like中所有必须加载的字符串这个：

protected void onCreate(Bundle savedInstanceState({super.onCreate(savedInstanceState(；setContentView(R.layout.alif_pics(；
```
preLoadText();
initilizeUi();
}
void preLoadText(){
// put all text stuffs
}
void initilizeUi(){
// put you main application code
}
```

您可以通过将其添加到您的oncreate方法中来隐藏背面图像按钮：

imgBut1.setEnabled(false);
imgBut1.setClickable(false);

其次，您可以将默认值存储在项目的/res/values/文件夹中的strings.xml文件中，以便以后可以保留这些值。

<string name="textview1_deafult">TextView1 Deafult value</string>

当计数器达到零时，您可以添加以下代码来禁用后退按钮：

// my previous ImageButton
public void previousClick() {
    try {
        imgBut1.setClickable(false);
        imgBut1.setEnabled(false);
        text1.setText(R.string.textview1_default);
        //and so on
    } catch (Exception e) {
    }
}

不要忘记使用带小写"s"的"字符串"R.string.textview1_default">

这应该可以完成
